HoneywellHome DT3 Wired Thermostat for Heating Control with Energy Efficient LED, No WiFi or App Required (Black)

I first bought this particular room thermostat from a local DIY store. My old analogue type was inefficient, it had a huge hysteresis so the boiler 'would never switch off' unless the house temperature was way above the level that was set.This digital thermostat, easy to install, is very efficient and switches the heating on and off at the correct temperature. ( a separate thermometer proves this).My daughter's family had similar problems in their house so I tried to get them the same item. The local DIY store had stopped selling this particular item and only stocked items that were more complicated and more expensive.I opted for the Amazon store to find the same model I had purchased. Bingo! Bought it, installed it into my daughter's house. My son-in-law is over the moon with the result. So much more efficient and their boiler is running less than before.Some people have reported difficulty in opening the device. I had no problem, but being an engineer found it easy. To remove the cover, for access to the batteries, place your thumb on the bottom of the unit, fingers on the top, and 'twist' down. Cover easily removed. For access to the electrics and fixing screws. Isolate the 240v mains to the unit from the boiler control or main switch for safety. Use a small screwdriver blade to 'gently' release the 2 top locking tabs at the top for the middle case to be lifted clear. Done. To reverse the procedure, 'Click' the middle case back. To replace the front case: place the bottom in first and then twist top back in. Pull to check it has locked. Done.

Had this thermostat for two years now and has continued to work well.

Easy to work. Looks good

Bought this to replace a much older controlled thermostat. Which had a lot more function's. Which were never used. It was always temporarily even from new. After several years it finally stopped working so I wanted to replace it with something better suited to what needed. This new thermostat is great so simple to use and install. Nothing fancy no timers no holiday mode. If you want a straight forward easy thermostat turn the heating on or off or just set the heating to the temperature you want. This is definitely recommend Looks good works really well. Had it over a month or so can't fault it

You may be misled to thinking this is a fully programable stat . It is not .You can adjust how long on i.e. 1,2,3etc 10,15etc when stat switches onAnd adjust of time when stat switches offit has no clock function or clock , so you can't set on periods for one temp (day), with night periods tempyou temp it keeps it at that with adjustments

We wanted to replace our old room thermostat and our plumber recommended this product. It looks much better and works well. We could really have used some instructions on how it worked. Online searches only produced a video in French! This is a comment for the maker. Good service from the seller.

Looks nice but... Keeps starting boiler several times per hour to not let temp down at all, What's increasing gas consumption.

Looks and works well with the bonus of being a well known reliable make.
